0.6.0

Breaking

• @Actor is renamed to @RemoteActor — a clean break, no deprecation alias. The wrapper names the authoring-model perspective: from the client island's point of view, the injected actor lives across the web boundary. (@ServerActor was rejected for its one-edit distance from @ServerAction.)

New

ActorScope — identity as a small algebra

Declare where a virtual actor's identity key comes from, instead of enumerating scope cases:

• .derived(_:_:) — the server derives the key from the trusted invocation context; authorization is identity-match, automatic. Presets: .application, .user, .tenant, .session.
• .addressed(authorization:) — the caller names the key (rooms, documents); an authorization policy is required by the type system.
• .transient — no durable identity.
• Scopes compose with + into composite identities (contract:user:<uid>:<entity>) with segment rules AND-ed.

ActorGroup(scope:) registers the scope's implied authorization; external invocations addressed outside the caller's derived prefix are denied.

Passivation and lifecycle hooks

• ActorGroup.passivation(.afterIdle(.minutes(5))) — per-contract idle passivation override.
• WebActorLifecycle: optional activated() (runs after grain state restore — cold start and resume are the same path) and passivating() (last work before hibernation; mutated state is persisted).
• Combining .transient with a passivation policy is a scene configuration error.

Durable reminders (Orleans-style)

• reminders.set(_:in:/at:), cancel, pending on any WebActorSystem actor.
• Reminders fire while the actor is passivated and re-activate it: state restore → activated() → WebActorRemindable.reminder(_:) → state save.
• WebActorReminderStore is the durable backend contract (Cloudflare host lowers onto Durable Object Alarms); InProcessActorReminderStore ships for native hosts and tests. Scheduling without a store throws.

@RemoteState (server core)

• @RemoteState("key") on a server actor publishes JSON-encoded RemoteStateChange values through the installed WebActorStatePublisher on every write, bound to the actor's identity at activation. The WebSocket host fans changes out to observing client islands.

Notes

• WebActorInvocationContext gains tenantID.
• 218 tests passing (205 Swift Testing + 13 XCTest macro tests).
